Zheflon ® PVDF for Lithium Battery Grade Applications
Binder for cathode electrodes
Application for LFP
LFP is a lithium ion battery cathode material with high safety and stability. PVDF can be used as a binder to bond LFP powder and conductive agents together.
Application to NCM523 and NCM622
NCM has higher safety as the cathode material. PVDF is used as a binder to bond the cathode material and the conductive agent (e.g. carbon black) together to form a homogeneous electrode film. PVDF provides good bonding performance and ensures a strong connection between the cathode material and the conductive agent, improving the performance and cycle life of the battery.
Application in NCM811
NCM has higher safety as the cathode material. The cathode of NCM811 batteries consists of a high ratio mixture of nickel oxide, cobalt oxide and manganese oxide. Due to the high nickel content of NCM811 batteries, their electrochemical reactions are more violent and require a stronger binder to maintain the stability of the electrode. PVDF as a binder provides excellent bonding properties, ensuring a strong connection between the cathode material and the conductive agent in NCM811 batteries, increasing the cycle life and energy density of the battery.
